Computer science change
In microscopy, visual artifacts are sometimes introduced when processing samples into slide form.
Remote sensing change
Medical imaging change
In medical imaging, artifacts are wrong representations of structure of tissues. They are made by imaging techniques such as ultrasound, X-ray, CT scan, and magnetic resonance imaging (MRI). These artifacts may be caused because of the energy-tissue interaction between ultrasound and air. Physicians usually learn to recognize some of these artifacts to avoid mistaking them for actual pathology.
Radar echoes from something causes ghost images to appear. All those echoes must be filtered in order to get the where the object is, how fast it is going and the type of object it is. It may include aircraft, and weather.
